KA040XP0 ultra thin wall four point contact ball bearing is designed for compact equipment requiring multi‑direction load‑bearing capacity. Its KA‑series square cross‑section realizes space‑saving installation. It bears radial, bidirectional axial and overturning moment loads. Ideal for collaborative robot joints,optical automation devices and precision rotary tables.
X-type four-point contact ball bearings - KA series feature an optimized four-point contact raceway geometry with a split inner ring and single outer ring design (or vice versa), allowing compact support of radial loads while accommodating high axial loads in both directions with minimal clearance. Available in standard, thin-section, and heavy-duty configurations, with bore diameters ranging from 25mm to 400mm. These bearings deliver high axial rigidity, compact design, reliable moment load capacity, and reduced system weight, making them ideal for slewing rings, industrial robot joints, crane turntables, packaging machinery, and precision rotary tables.
